What We Know About America’s Billionaires: 1,135 and Counting

“Billionaire” evokes tech founders such as Jeff Bezos or Bill Gates , but there is a large and growing group of people worth at least $1 billion in small towns and big cities that rarely make the headlines.

There were 1,135 billionaires in the U.S. as of 2024—up from 927 in 2020, according to data from Altrata, a wealth-intelligence firm. The biggest concentration, 255 of them, is in California. But the super rich are also behind businesses in places such as Ridgeland, Miss., and Waunakee, Wisc.

Collectively, these people are worth about $5.7 trillion, according to Altrata’s estimates. That’s enough wealth to buy…

While many of these individuals own properties in upscale communities such as Palm Beach, Fla., they also congregate in destinations such as Cashiers, N.C.—a town in the Blue Ridge Mountains where four billionaire families have residences. The smallest town where a billionaire owns property? Winifred, Mont., population 172.

The list of billionaires includes some familiar dynasties, such as the Walmart Waltons and Hyatt Pritzkers. There are also lesser known members of this elite club, such as Diane Hendricks , co-founder of roofing-products distributor ABC Supply, and the heirs to the Russell Stover Chocolates fortune.

The billionaire border can be fuzzy. Markets fluctuate, the value of private companies can be uncertain and big donations dent fortunes, meaning dozens of individuals—even stars such as LeBron James and Beyoncé—can move on or off the list.

The 100 richest billionaires account for nearly $3.86 trillion in wealth—more than half the total. Just three men— Elon Musk , Bezos and Mark Zuckerberg —account for almost $1 trillion of it.

Despite those outsize Silicon Valley fortunes , most U.S.-based billionaires didn’t make their wealth in tech. About 300 came from banking and finance, compared with roughly 110 from the tech sector. Another 75 came from real estate.

A third of billionaires inherited much or all of their wealth, Altrata said. There is just one Rockefeller on the list, but 50 billionaire heirs of five companies hold roughly $830 billion total. These individuals account for nearly 15% of all the billionaires’ wealth. undefined

Billionaires have publicly donated or pledged to give about $185 billion since 2015, according to Altrata. Mostly, they support causes such as education and medical research—they gave $90 billion to those two in the past 10 years. That has given them sway in ongoing campus debates over freedom of speech and antisemitism.

While some billionaires such as Gates and Warren Buffett have openly pledged to give away much of their wealth , others have donated little so far. About a quarter of the billionaires in the list have known donations of less than $1 million in the past decade.

Some give more to organizations they’re tied to. Hedge-fund manager Bill Ackman gave about $120 million to multiple causes, but he gave $1.36 billion to a foundation where he and his wife serve as trustees, which supports medical research and other causes.

Among the top recipients of donations tracked by Altrata are global charities such as the Gates Foundation and Gavi, the Vaccine Alliance.

One of the most popular recipients is the Central Park Conservancy in New York, which received donations from 89 billionaires worth about $100 million.

Johns Hopkins University received $7.5 billion from close to 30 billionaires, but most of it came from Michael Bloomberg , who gave more than $5 billion.

Methodology

The Wall Street Journal analysed data on more than 1,100 individuals provided by Altrata, which estimates net worth by assessing privately and publicly held businesses and investible assets. Altrata’s data on properties includes residences, land parcels and other properties owned in the person’s name. It uses primary business address to determine a billionaire’s location and assigns each billionaire to a primary industry based on their current roles. Altrata adjusts totals to account for shifts in asset values that could push some individuals over or under $1 billion in wealth.

Every year, thousands of Australians make the decision to pack up life overseas and come home.

After years, sometimes decades, building careers, accumulating assets, and growing families in places like Dubai, London, Singapore, or Hong Kong, the pull back is understandable.

What most don’t appreciate until it’s too late is that the return journey is often far more financially complex than the departure.

Leaving Australia is, financially speaking, a relatively clean event.

You depart, you potentially become a non-resident for tax purposes, and a new set of rules applies.

Coming back, however, means reconciling everything you’ve accumulated offshore with an Australian tax system that hasn’t been standing still waiting for you.

The Tax Residency Trap

The first and most costly mistake is misunderstanding when Australian tax residency resumes.

Many returning expats assume residency only kicks in once they’ve formally re-established themselves, signed a lease, updated their address, started a job. The ATO doesn’t see it that way.

Under Australian tax law, residency can recommence the moment you land with the intention of remaining. That means any taxable events, investment income, asset disposals, foreign account distributions that occur after that point are potentially assessable in Australia, even if they’re sitting in offshore accounts you haven’t touched.

Superannuation: The Clock Doesn’t Stop

One of the most underappreciated issues for returning expats is what’s been happening inside their superannuation fund while they’ve been away.

Contributions may have paused, but fees, insurance premiums, and investment volatility haven’t. Some returning clients are genuinely shocked by how much ground their super has lost to fees during periods of lower balances or inappropriate investment settings.

The more strategic issue is what to do on the way back. If you hold foreign pension arrangements, a UK SIPP or QROPS, a 401(k), and international savings schemes, the question of whether and how to repatriate those funds requires careful planning before you return.

Once you’re a tax resident again, distributions from certain foreign structures can be assessable as ordinary income, and the window to manage that exposure closes.

Offshore Investments Don’t Disappear

Returning to Australia doesn’t sever your obligations in the countries where you’ve been living.

Foreign-held shares, managed funds, or investment accounts will be picked up by Australian tax reporting requirements from the moment residency resumes.

The Foreign Investment Fund rules, transferor trust provisions, and the reporting obligations under Australia’s tax information exchange agreements mean these holdings need to be declared and, in some cases, restructured.

Leaving investments sitting offshore in structures that made sense as a non-resident but create compliance headaches as a resident is one of the most common and expensive mistakes we see.

The restructuring cost, if it’s even possible post-return, typically dwarfs what it would have cost to plan properly in advance.

Property: Both Sides of the Balance Sheet

There are two distinct property problems for returning expats.

The first is what they’ve held while away, an Australian property rented out during the absence.

Depending on how long the property was the main residence and how it was treated during the rental period, the CGT calculation on eventual sale can be complex.

The six-year absence rule provides some relief, but it’s not automatic and has conditions that are frequently misunderstood.

The second is re-entry into the Australian property market.

After years of asset accumulation offshore, many returnees assume they’re well-positioned to buy.

The challenge is that their financial picture, including foreign income history, offshore assets and currency, doesn’t translate neatly into Australian mortgage serviceability.

Lenders read foreign income conservatively, and what looks like a strong balance sheet can create unexpected borrowing capacity issues.

The Fix: Plan Before You Land

The single most effective thing an expat can do is start planning the return 12 to 18 months before departure.

That timeline allows for managed asset disposals under non-resident rules where advantageous, superannuation catch-up strategies, foreign structure rationalisation, and property decisions that aren’t being made under time pressure.

The irony is that most Australians sought financial advice before they left on how to exit cleanly.

Far fewer seek the same rigour on the way back in. Given the complexity involved, that’s an expensive oversight.

Coming home should be a financial clean slate. With the right planning, it can be. Without it, you’ll spend the first few years back unwinding decisions that didn’t have to be problems at all.
